STU M P-EXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 48,209, dated August31, 1886.

Application filed April 12, 1886.

To all whom it may concern:

Be it known that I, J OSEPH DANIEL HnNs- LEY, a citizen of the UnitedStates, residing at Rogers, in the county of Benton and State ofArkansas, haveinvented a new and useful Improvement in Stump-Extractors,of which the following is a specification.

My invention relates to an improvement in stump-extractors; and itconsists in the peculiar construction and combination of devices, thatwill be more fully set forth hereinafter, and particularly pointed outin the claims.

In the drawings, Figure 1 is a perspective View of my invention. Fig. 2is a side elevation of the same, showing the operating-lever in oneposition in solid lines and in another position in dotted lines. Fig. 3is a side view of the same, the lever being shown in dotted and alsofull lines.

The object of my invention is to provide a cheap and simple apparatusfor extracting the roots or stumps of trees from the ground; and thisobject I attain by the construction hereinafter described.

A represents the vertical frame, which is provided on its upper side, atits center, with vertical standards B, which are arranged at a suitabledistance apart, and are each provided with two vertical series ofopenings, a and b, the series of one standard aligning with thecorresponding series of the opposing standard. A cross-piece, D,connects the upper ends of the standards B. The frame is provided withdiverging supporting-legs at its corners E, the lower ends of which areconnectedin pairs by means of runners F, which extend parallel to eachother and transversely across the longitudinal axis of the frame. Fromopposite sides of the frame project handles G.

H represents a double-ended lever, which fits between the standards B,and is provided at its center with a depending hook, I, at the lower endof which is attached the elevatingchain K. To the lower end of the chainis attached a pair of connecting-chains L, which latter have their lowerends attached to the upper ends of the arms M of a grapple, N, havingpivoted jaws O.

R and S represent a pair of pins, which are adapted to be passed throughthe vertical openings a and b of the standards.

The operation of my invention is as follows: The frame is moved so as tobring the stand ards directly in vertical line with the stump to beextracted, and the grapples are caused to engage with the stump. One ofthe pins is then passed through aligned openings a under the lever, thelatter being raised sufficiently to draw the elevating-chain taut whenthelever is in a horizontal position. The pin thus forms the fulcrum forthe lever, and the latter is inclined to the position shown in solidlines in Fig. 2, which raises the lower side of the central portionabove aligned openings 1) in the standards. The other pin is theninserted through the said openings and forms the fulcrum for the lever,the lower pin is withdrawn, and the lever is moved to the positionindicated in dotted lines in Fig. 2, thereby partly elevating the stump.The disengaged pin is then inserted through aligned openings a under thelever, and the latter is moved or tilted in the direction indicated insolid lines in Fig. 2, 'when the operation before described is repeateduntil the stump has been entirely extracted from the ground. It will beobserved that the vertical series of openings or and b and the pinsadapted to be inserted in said openings form a series ofvertically-ascending fulcrums for the lever, thus permitting the latterto be operated and constantly raised until it reaches the upper ends ofthe standards, as will be readily understood. As the distance from theresistance (indicated by the hook I) to the fulcrum formed by one of thepins is very slight, and as the outer ends of the lever are at aconsiderable distance from the centerthereof, it will be seen that verygreat leverage may be exerted in raising the stump with very slightexertion on the part of the operator.

Having thus described my invention, I claim- 1. The combination of theframe having the vertical standards provided with the vertical series ofopenings or and b, the pins adapted to be inserted in the said openings,and thereby form a series of ascending fulcrums, and the double-endedlever arranged to operate on the pins or fulcrums, for the purpose setforth, substantially as described.

2. The combination of the frame having the supporting-runners and thehandles, and provided with the vertical standards having the verticalseries of openings a and b, the pins adapted to be inserted in the saidopenings, the double-ended lever, the elevating-chain attached to thecenter thereof, and the grapple attached to the lower end of the chain,for the :0 purpose set forth, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses. I
